Flow assurance consulting Flow assurance (FA) is the science and engineering of predicting and managing production behavior as fluids move from the reservoir to the market through the changing environment of the reservoir and production systems. Changes in production are rarely avoidable because oil and gas fields mature and decline. Solids may form in wells and flowlines, gas or water cut may increase, and reservoir pressure may fall. The OneSubsea flow assurance consulting team focuses on the entire fluid journey from the reservoir pore space to the topside facilities and from exploration to abandonment. Optimal FA design and operations require a detailed understanding of the fluid, reservoir, well, pipeline gathering system, surface facilities, and surrounding environmental conditions. Based on our in-depth knowledge of multiphase fluid flow dynamics and all related technical disciplines, our FA offerings comprise fluid chemistry and processing, production engineering, surveillance, and operations. Our unique and fully integrated approach focuses on the design and operational changes of the entire subsea production system, which helps to optimize production and enhance ultimate recovery.

TCP/IP technology, we can connect all current and future devices to a fully Subsea control systems and their related ancillary equipment are critical integrated control system.

10 Tree and manifold controls The OneSubsea tree and manifold controls are designed for a wide variety of field functionalities. Their modular setup enables the use of field-proven subcomponents, providing high flexibility and high reliability. Our subsea control modules (SCMs) are qualified in accordance to API Spec 17F and ISO 13628-6, International Welding Inspection (IWI), and Subsea Instrumentation Interface Standardization (SIIS) and are designed to handle a variety of subsea instruments. Accommodating AC and DC power and using copper or fiber-optic communication, OneSubsea tree and manifold controls can connect distances in excess of 124 mi [200 km] while using low-voltage range connectors.

Multiphase pump controls A seabed boosting system is a dynamic system that requires active control of the multiphase pump to ensure optimal performance. The basis for the control system is the EH MUX* subsea electrohydraulic multiplex system, seamlessly integrated with a programmable logic controller (PLC)–based pump system located topside. A high-speed fiber-optic topside-to-subsea Ethernet communication system enables closed-loop control and fast-acting safeguarding of the seabed booster pumps. The SCM can be configured with up to 28 hydraulic functions and offers SIIS Level 1–, 2–, and 3–compliant interfaces for process sensors and other subsea devices.

Multiphase flow controls The OneSubsea multiphase flow monitoring system is based on a retrievable subsea module that acts as a hub for up to six PhaseWatcher flowmeters with Vx technology. This unique module distributes switchable power to the individual flowmeters and provides an Ethernet IP backbone communication path to the topside. The data from the individual flowmeters are stored in a data server that is located topside. The system seamlessly calculates the combined flow rates and fractions and also provides a single interface for the transfer of data to the external systems. Not only does the interface include interactive mirrored screens with well testing functionality, but it also provides complex trending capabilities and automated reporting functions.

Topside and FPSO controls OneSubsea topside and FPSO vessel controls are reliable and robust and use commercially available components. They can be easily interfaced with the supervisory control system of the host facilities. Backward compatibility and provisions for obsolescence ensure integrity of the system during its field life. As the standard for our production control systems, OneSubsea uses a Linux®-based operating system that has set industry benchmarks with respect to functionality, scalability, and software robustness. In addition, the control system offers a remote monitoring feature and access to a 24/7 call center for main control station software support.

Wet-mateable Diamould connectors OneSubsea Diamould* electrical connectors provide a reliable connection throughout the subsea production system, whether delivering power to an ESP or enabling communication from a downhole intelligent completion. These connectors use pressure-compensating, oil-enclosed chambers around the contact pins, improving system reliability and eliminating the corrosion and contamination generally associated with exposed-pin connectors. Unique electrical stress control management in every connector enhances the overall electrical performance. Dual-contact instrumentation connectors enable advanced downhole telemetry systems for intelligent completions.

11 Swivel and Marine Systems

When an FPSO unit is operating in rough weather or rising and falling seas, it needs to be moored with a turret system, enabling the FPSO vessel to rotate or weathervane around its fixed mooring. Generally, a fluid swivel system on top of the turret handles both the large volumes and high pressures of the production and injection fluids that flow through it.

OneSubsea offers a swivel system for any type of FPSO application. Swivel flowlines, manifolds, and risers to the rotating vessel and its process plants stacks are critical elements onboard an FPSO facility. Swivels ensure under virtually any environmental conditions. that all fluids, controls, and power are transferred safely from the wells,

12 Swivel stacks OneSubsea swivel technology is a fully integrated and compact fluid transfer system for oil and gas production, fitting any turret and any FPSO, floating storage and offloading (FSO), or floating LNG (FLNG) vessel. Compact and lightweight, the system requires minimal space and structural support. Our swivels are used to transfer liquid, multiphase fluids, or pure gas using the same swivel and fluid sealing technology. It offers high-capacity and high-pressure capabilities up to 7,500-psi [517-bar] gauge pressure and design temperatures to more than 212 degF [100 degC]. Sealing between process fluids and the environment is provided by remotely pressurized barrier-fluid-activated dynamic seals. The design features primary and secondary seals, which ensures continuous monitoring and protection of the natural environment.

Turrets OneSubsea internal turret technology was developed more than 20 years ago for the challenging North Sea environment to ensure that vessels stay connected at a 100-year condition of maximum 98-ft [30-m] wave height and 135-ft/s [41-m/s] wind. The turret technology has been in operation on more than 10 fields in extremely harsh environments. The system offers multiriser capabilities with effective in situ adjustments and replacement of mooring lines. The same applies for the pull-in and replacement of risers and umbilicals. The turret design includes a robust bearing arrangement for horizontal and vertical loads using low-friction wheel-type upper axial and radial designs and a segmented pad-type lower bearing arrangement.

Submerged loading systems OneSubsea loading systems are fully submersible and enable the transfer of processed crude from the production and processing facilities to a dynamic-positioning-based shuttle tanker. The system consists of a riser base, rigid riser, buoyancy tank with swivels, loading hose, and pickup system. The riser base contains connectors for two flexible flowlines, valves, and a control system to communicate with the processing facilities. The riser has a flexible joint at the lower end and is held in tension by the buoyancy tank. A swivel is placed at the top to allow the loading hose and shuttle tanker to freely weathervane. The loading system offers a large operating envelope and is based on the use of standard field-proven components with a service life of 25 years and a low degree of maintenance. The system is located subsurface and is subject to low environmental loads and motions.

Offshore cryogenic transfer OneSubsea offshore cryogenic transfer (OCT) technology is based on a tandem ship-to-ship configuration that has been used successfully in offshore oil transfer for more than 30 years with more than 20,000 loading operations carried out worldwide. Because the OCT system can accommodate a separation distance to 328 ft [100 m], large relative movements are allowed by both the producer (FLNG vessel) and the LNG carrier. The system consists of an A-frame crane extending from the stern of the FLNG vessel toward the bow of the LNG carrier. Three corrugated stainless steel vacuum-insulated flexible pipes hang from the tip of the crane to the bow of the LNG carrier. Two of the flexible pipes are used for LNG, and one is used for a vapor return loading facility in the bow. Maximum wave heights during connect and disconnect are 15 ft [4.5 m] (Hs) and 18 ft [5.5 m] (Hs), respectively.
